3201482 - IP67 Quick-Lock - Industrial EMC Shielded Stainless - Circular

Product Specification

Product Overview​

The Phoenix Contact ​3201482​ is a high-performance surge protection module designed to safeguard sensitive industrial automation equipment from voltage spikes, transient overvoltages, and electromagnetic interference (EMI). Part of Phoenix Contact’s TRABTECH series, this device ensures reliable protection for control systems, communication networks, and power supplies in harsh environments. Its compact, DIN rail-mountable design (EN 60715) allows seamless integration into control cabinets, motor control centers, and switchgear panels. The module features a robust polycarbonate housing with ​IP20 protection, providing resistance to dust and mechanical impacts.

Engineered for universal compatibility, the 3201482 supports a wide range of industrial applications, including PLCs, sensors, and communication interfaces. Compliance with ​IEC 61643-11, ​UL 1449, and ​RoHS/REACH​ standards ensures global safety and environmental compliance. Visual status indicators (green/red LEDs) provide real-time monitoring of protection status, simplifying maintenance and fault detection.

​Key Technical Parameters​

The 3201482 is defined by precision-engineered specifications for surge protection:

• ​Rated Voltage: 24 V DC / 48 V DC (for control circuits).
• ​Maximum Discharge Current (Imax)​: 10 kA (8/20 µs pulse), ensuring robust protection against lightning-induced surges.
• ​Voltage Protection Level (Up)​: <60 V (for 24 V DC systems), minimizing risk to sensitive electronics.
• ​Response Time: <1 ns, providing near-instantaneous reaction to transient events.
• ​Operating Temperature: -40°C to +80°C, suitable for extreme industrial environments.
• ​Connection Type: Screw terminals for secure, vibration-resistant wiring (0.2–2.5 mm² conductor cross-section).
• ​Certifications: UL 1449 (Type 4), CE, and IEC 61643-11 (surge protective devices).

These parameters make the 3201482 ideal for protecting low-voltage control systems and communication networks.

​Primary Applications​

The 3201482 is critical in safeguarding automation infrastructure across industries:

• ​PLC and Controller Protection: Shields I/O modules and control logic from voltage surges in manufacturing and robotics.
• ​Sensor Networks: Protects analog/digital sensors in process automation (e.g., chemical plants, water treatment).
• ​Communication Lines: Secures RS-485, Ethernet, and fieldbus systems (PROFIBUS, CANopen) in industrial networks.
• ​Renewable Energy Systems: Protects solar inverters and wind turbine controllers from lightning-induced surges.
• ​Transportation Infrastructure: Ensures uninterrupted operation in railway signaling and traffic control systems.

Its compact design also suits mobile machinery, packaging lines, and semiconductor manufacturing, where space constraints and electrical noise are prevalent.

​Competitive Advantages​

The 3201482 excels through innovative surge protection technology and user-centric design:

• ​High Surge Capacity: Handles up to ​10 kA​ discharge current, exceeding industry standards for critical systems.
• ​Visual Status Monitoring: Dual-color LEDs provide instant feedback on module health and failure alerts.
• ​Tool-Free Replacement: Modular design allows quick swap without disconnecting adjacent components.
• ​Universal Compatibility: Works with 24 V DC to 48 V DC systems, reducing inventory complexity.
• ​Durability: Flame-retardant housing (UL94 V-0) and corrosion-resistant terminals ensure long-term reliability.

These features minimize downtime, protect costly equipment, and reduce maintenance costs in mission-critical installations.

​Functional Features​

The 3201482 delivers advanced surge protection capabilities:

• ​Multi-Stage Protection: Combines gas discharge tubes and varistors for coordinated suppression of fast and slow transients.
• ​Thermal Disconnect: Automatically disconnects from the circuit upon overload to prevent fire hazards.
• ​Compact Design: Space-saving footprint allows high-density installations in control panels.
• ​Easy Diagnostics: Replaceable modules with snap-on DIN rail mounting simplify troubleshooting.
• ​Galvanic Isolation: Reduces ground loop interference, ensuring signal integrity in sensitive circuits.

Combined with Phoenix Contact’s rigorous testing standards, the 3201482 ensures uninterrupted operation and compliance with global safety regulations.
